Thank you all for the feedback and support!

This is only the first half of the update. The second half is currently in development and is planned to arrive within the next 1–2 weeks.

If you encounter any bugs or issues, please let me know. Your feedback helps shape the game and makes it better for everyone.

First of all, thank you everyone for the support! We've now reached 300 concurrent players after one week, which is something I never expected. Seeing so many people playing, sharing feedback, and reporting bugs has been incredibly motivating.

I've been reading all your comments, reviews, bug reports, and suggestions. Before I start working on the next major update (mentioned in my previous post), there are a few important things I want to improve first.

Since I'm developing everything by myself, it takes some time to go through all the feedback and figure out the best solutions, but I want you to know that I'm listening.

1. Difficulty Adjustments

The biggest complaint I've seen so far is the game's difficulty, especially during the early stages.

Planned Improvements

• Scammer Guide Book

  • An in-game guide that teaches new players how to survive and manage debt effectively.

• Difficulty Settings

  • Easy Mode: No loan interest.

  • Normal Mode: Current experience.

  • Hard Mode: Higher interest rates for players looking for an extra challenge.

2. Game Experience Improvements

Many players have pointed out that holding tools and weapons feels awkward because it works the same way as carrying boxes.

Planned Improvements

• Rework how tools and weapons are held.

• Make using equipment feel smoother and less frustrating.

3. Skeletons... 💀

Yes, I've seen the comments.

A lot of comments.

About skeletons.

Planned Improvements

• Introducing a Bone Collector occupation to help manage all those skeletons and reduce the workload.

• New Ritual Item, sacrifice skeletons in your own house for... reasons. Totally normal scammer activities.

• I'm not going to completely remove the ability to ride skeletons. Honestly, I think it's pretty funny. However, I'll try to improve the experience and reduce some of the more annoying collision issues that come with it.

4. Bugs, Bugs, and More Bugs

Because of the limited testing time before launch, I know there are still bugs hiding everywhere.

I'm fixing them as fast as I can. I can't promise the game will ever be completely bug-free, but I'll continue patching issues and improving stability with every update.

There are more improvements on the way, and I'll keep sharing progress as development continues.

Thank you again for all the support, patience, feedback, and bug reports. Every message helps make the game better.

See you in the next update!

Thank You, Scammers!

The past week has been absolutely crazy for me.

Before launch, I was so busy getting everything ready that there simply wasn't enough time for proper testing. As a result, the game launched with several critical bugs and issues. Thankfully, most of the major problems have now been fixed, and I'll continue releasing patches and improvements over the coming weeks.

For the first time since launch, I can finally start focusing on new features and content updates!

I want to give a huge thank you to everyone who has submitted bug reports, feedback, suggestions, and ideas. Every report helps make the game better, and I genuinely appreciate the time you've taken to help improve it.

When the game launched, we had around 100 concurrent players. One week later, we're seeing over 200 concurrent players. The numbers may not seem huge compared to some games, but for me, it's incredibly motivating and gives me even more reason to keep pushing forward.

I promise there will be at least three major content updates before the full release. The official launch is currently planned for somewhere between 6 months and 1 year from now, depending on development progress.

Please continue letting me know whenever you encounter bugs, issues, or have suggestions. I know the game isn't perfect—far from it—but I want to keep improving it together with all of you.

See you in the next update!

• Fixed issues with achievement triggers not registering correctly
• Fixed cursor disappearing during gameplay

Dear scammers and players,

After 1.5 years of solo development, Scam Center Simulator: UnderKingdom is finally here. Honestly, it still feels unreal to finally release this game.

What started as a small idea slowly grew into something much bigger than I ever imagined.

Throughout development, there were a lot of moments that kept me motivated, seeing positive feedback from players, getting thousands of wishlists within a week, and the excitement of finishing new features one by one. Those moments made all the hard work worth it.

But there were difficult moments too. The game was banned across Chinese social media, hundreds of videos were removed, news media criticized the game, it genuinely felt like a nightmare.

Still, none of that changed why I started making this game in the first place. Making a game that I truly wanted to create has always mattered more to me than anything else.

Thank you to everyone who supported me throughout this journey. Even though the game already has enough content to be considered a full release, there's still so much more I want to add. That's why I decided to launch in Early Access, so I can continue growing the game together with the community.

Here's a draft roadmap for the upcoming updates. A more detailed version will be announced after I've collected enough feedback from the community.

Thanks again, and I hope you all enjoy the game.

If you run into any bugs or issues, feel free to let me know. You can find me in the Discord or QQ group, I'm active there.

Regards,

Jiao
